Specification of Letters Patent.

Patented July 19, 1 91 0.

To all whom it may concern:

Be it known that l, Ci-IAaLns W. FnLKnn, a citizen of the United States,residing at Argentine, in the county of Wyandotte and State of Kansas,have invented certain new and useful Improvements in Lawn-Mowers, ofwhich the following is a specification.

My invention relates to improvements in lawn mowers.

One of the objects of my invention is to provide a lawn mower that willreadily cut grass of any height.

Another object of my invention is to provide a lawn mower with means bywhich the cut grass may be blown rearwardly from the grass cuttingmeans.

Other novel features of my invention are hereinafter fully describedvand claimed.

In the accompanying drawings which illustrate the preferred form of myinvention-Figure 1 is a vertical sectional view, taken on the dottedline a-b of Fig. 2. Fig. 2 is a front elevation of my improved lawnmower. Fig. 3 is a horizontal sectional view, taken on the dotted linec-6Z of Fig. 1, some of the parts being broken away. Fig. l is afragmental, vertical sectional view taken on the dotted line c-f of Fig.2, looking in the direction denoted by the arrow, adjacent to saiddotted line, which points to the right- Fig. 5 is a fragmental, verticalsectional view, taken on the dotted line c-f of Fig. 2, looking in thedirection indicated by the arrow, which points to the left. Fig. 6 is ahorizontal sectional View, taken on the dotted line gba of Fig. 1.

Similar characters of reference denote similar parts.

1 denotes a horizontal axle upon which are rotatively mounted carryingwheels 2 and 3. The axle is provided with two parallel, downwardlyextending arms, 4l and 5, to which is secured a horizontal bar 6, fromthe forward edge of which extend a plurality of horizontal cutting teeth7. Upon the upper side of the toothed bar G is a sickle bar 8, which onits forward edge is provided with a plurality of horizontal cuttingteeth 9, which rest upon and coperate with the teeth 7 of the bar 6. Thesickle bar 8 is reciprocatively mounted and has secured to its upperside a yoke 10, to which is pivotally secured one end of a pitman 11,the other end of which is secured to the crank 12 of a rotary horizontalshaft 18, mounted upon the arm 1l. To the shaft 13 is secured a pinion14, which meshes with a circular row of crown teeth 15, provided on theinner side of the rim of the carrying` wheel 2.

To blow rearwardly the cut grass from the sickle bar S, I provide a fan,preferably of the rotary type, the fan being operated by one of thecarrying wheels. The fan which l have illustrated in the drawings isprovided with a horizontal shaft 16, rotatively mounted in the arms 4and 5, and having secured to it a pinion 17 which meshes with a circularrow of internal gear teeth 1S, provided on the inner periphery of therim of the carrying wheel 3. On the shaft 1G are secured two hubs havingradial arms 19 to which are secured respectively a series of horizontalpaddles 20, disposed parallel with the shaft 16. The shaft 16 isdisposed forward of and above the sickle bar 8 so that when the shaft isrotated by the forward movement of the lawn mower, the paddles 20 willblow cut grass rear wardly from the sickle bars S. A series ofhorizontal plates 21 are secured at their rear ends to the upper side ofthe bar 6, above the sickle bar 8, their forward ends being downwardlyturned over the forward edge of said sickle bar. The plates 21 serve asg'uides for the sickle bar. A small centrally disposed carrying wheel 22is rotatively mounted on a horizontal bolt 23, as shown in Figs. 1, 2and 5, said bolt being vertically adjustable in two slots 24, providedone in each of two rearwardly extending projections 25, on the rear sideof the toothed bar 6. On the bolt 23 is provided at each end thereof, anut 2G. Said nuts bear respectively against the outer sides of theprojections 25. By loosening one of the nuts 2G the bolt 23 may bevertically adjusted so as to lower or raise the teeth 7 of the bar 6.The axle 1 is provided with two rearwardly extending arms 27, to whichare secured respectively, two arms 2S, which in turn are rigidly securedto a handle 29, shown in Fig. 2, by which the axle 1 is tilted or movedforward or backward.

In operating my invention, when the machine is moved forward, thecarrying wheel 2 will rotate the pinion 14, thereby rotating the crankshaft 18 and reciprocating the sickle bar 8 through the intermediacy ofthe pitman 11. When the mower is moved forward and the carrying wheel Srevolved, the fan shaft 16 will be rotated by means of the pinion 17,thus causing the paddles 2O to blow grass cut by the sickle bar 8rearwardly and out of the way of the knives 9 or teeth 7.

I do not confine my invention to the speciiic structure illustrated anddescribed, as various modifications, within the scope of the appendedclaims, may be -made without departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. In a lawn mower, the combination with two rotarycarrying wheels, one of which is provided with a concentric circular rowof teeth, of an axle supported by said carrying wheels, grass cuttingmeans supported. by said axle, means actuated by one of the carryingwheels for operating said cutting means, a fan having a rotary shaftdisposed so that the fan will blow the cut grass rearwardly from saidcutting means, and a pinion secured to said shaft and meshing with saidteeth.

2. -In a lawn mower, the combination with two rotary carrying wheels oneof which is provided with a concentric circular row of teeth, of an axlesupported by said carrying wheels, a reciprocative sickle bar, means forsupporting said sickle bar from said axle, means actuated by one of saidcarrying wheels for reciprocating the sickle bar, a fan having a rotaryshaft disposed so that the fan will blow cut grass rearwardly from saidsickle bar, and a pinion secured to said shaft and meshing with saidteeth.

3. In a lawn mower, the combination wit-h two toothed carrying wheels,of an axle supported by said carrying wheels, two pinions meshingrespectively with said toothed carrying wheels, a reciprocative sicklebar, means for supporting said sickle bar from said axle, a crank shaftsecured to one of said pinions, a pitman connecting said crank shaft andsickle bar, and a fan having a rotary shaft disposed so that the fanwill blow cut grass rearwardly from said sickle bar, said fan shaftbeing secured to the other of said pinions.
